I believe the answer is:
anaemic
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">bloodless</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for anaemic that I've seen before include "Lacking in red corpuscles" , "Suffering from lack of red corpuscles in blood" , "Deficient in red cells" , "strangely pale" , "Pallid, lacking vigour or colour" .)
